Description

Technical Field

[0001] The present invention relates to the technical field of mine surface monitoring, and in particular to a mine surface subsidence and rock movement observation device and a use method thereof. Background Art

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. A mine mainly includes one or more mining workshops (also called pits, mines, open pits, etc.) and some auxiliary workshops. Most mines also include ore dressing plants.

[0003] When mining, the terrain will be destroyed, both on the surface and underground. Therefore, mining is generally not allowed in places where humans live. During the mining process, changes in the terrain may cause surface subsidence. Underground mining may also cause rock movement and other phenomena. These phenomena will have an impact on the surrounding areas of the mining area. Therefore, observations are needed to ensure that possible environmental problems are observed and predicted.

[0004] Existing observation devices generally use probe-like devices to insert into the ground. Therefore, some holes are usually dug on the surface to facilitate the insertion of the observation device. Sometimes, the observation device is placed in existing surface cracks so that subsequent changes in the cracks or holes can be recorded. In order to ensure the stability between the observation device and the hole or crack, a device that can penetrate the inner wall of the crack is used to locate the observation device, or a structure that can stably position the observation device is installed on the surface. The latter observation device will be restricted in depth by the stabilizing mechanism on the surface, so the observation data takes priority. After the former observation device goes deep into the ground, a separate control device is required to control the positioning.

DETAILED DESCRIPTION

[0053] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0054] Example 1: Please refer to Figure 1-9 , a mine surface subsidence and rock movement observation device according to an embodiment of the present invention comprises an outer casing 1, the top end of the outer casing 1 is closed, and a handle 2 is fixedly installed on the top end of the outer casing 1, a motor sleeve 3 is fixedly installed on the top center of the outer casing 1, a sealing door 4 is installed at the bottom opening of the outer casing 1, a telescopic mechanism 5 is installed inside the outer casing 1, and an observation component 7 is fixedly installed on the bottom end of the telescopic mechanism 5. The telescopic mechanism 5 can drive the observation component 7 to extend out of the outer casing 1 and then pass through the opened sealing door 4 to realize the observation of the inside of the surface gap. In order to further ensure the stability of the outer casing 1 in the surface gap, a positioning mechanism 6 is also installed at one end of the inner part of the outer casing 1 close to the motor sleeve 3, and the outer side of the positioning mechanism 6 can pass through the side wall of the outer casing 1 and then contact the rock wall inside the surface gap, thereby realizing the stable positioning of the outer casing 1.

[0055] In order to enable the sealing door 4 to be automatically opened according to the extension of the observation component 7, and automatically closed when the observation component 7 returns to the outer casing 1, in this embodiment, the sealing door 4 includes a plurality of fan-shaped plates 14, and a hinge ear 15 is fixedly installed on the outer side wall of the fan-shaped plate 14. The outer bottom of the outer casing 1 is fixedly installed with hinge seats 8 that are equal to and one-to-one with the fan-shaped plates 14. A hinge shaft 11 is fixedly installed on the hinge seat 8. The end of the hinge shaft 11 away from the hinge seat 8 is rotatably installed on the hinge ear 15, and a torsion spring 12 is also sleeved on the hinge shaft 11. One end of the torsion spring 12 is fixedly installed on the hinge seat 8, and the other end of the torsion spring 12 is fixedly installed on the hinge ear 15. When the observation component 7 is extended, the end of the observation component 7 can push the fan-shaped plate 14. At this time, the fan plate 14 can be flipped around the hinge seat 8 through the hinge ear 15, thereby opening the bottom of the outer casing 1, so that the telescopic mechanism 5 can drive the observation component 7 to extend out of the outer casing 1 for observation.

[0056] In order to enable the positioning mechanism 6 to pass through the interior of the outer casing 1, in this embodiment, a strip hole 9 is opened on the outer wall of the outer casing 1, and the strip hole 9 is arranged coplanar with the positioning mechanism 6, and an air hole 10 is also opened on the outer wall of the outer casing 1, and the air hole 10 is arranged between the strip hole 9 and the top end of the outer casing 1, and the air hole 10 is arranged obliquely. In order to ensure that the telescopic mechanism 5 can stably telescope inside the outer casing 1, a first slide rail 13 is also fixedly installed on the inner wall of the outer casing 1, and the first slide rail 13 is arranged along the length direction of the outer casing 1. The observation component 7 includes a mounting seat 18, one end of the mounting seat 18 is fixedly installed on the bottom end of the telescopic mechanism 5, and an end of the mounting seat 18 away from the telescopic mechanism 5 is fixedly installed with a mounting plate 19, and the mounting plate 19 is far away An observation instrument 20 is fixedly installed on one end surface away from the mounting seat 18. In order to prevent the observation instrument 20 from colliding with the fan-shaped plate 14 when extended, an anti-collision rod 21 is fixedly installed on the outer side of one end surface of the mounting plate 19 away from the mounting seat 18. The number of anti-collision rods 21 is equal to the number of fan-shaped plates 14 and corresponds one to one. At the same time, in order to enable the fan-shaped plates 14 to be stably pushed open by the anti-collision rods 21 when opening, in this embodiment, an extension slide rail 16 is fixedly installed on one end surface of the fan-shaped plate 14 facing the inside of the outer casing 1, and when the fan-shaped plate 14 is fully opened, the extension slide rail 16 is arranged in the same line with the first slide rail 13, and a guide strip plate 17 is further provided on the end of the extension slide rail 16 away from the hinged ear 15, and the end of the guide strip plate 17 away from the extension slide rail 16 is fixedly installed on the fan-shaped plate 14. When the observation instrument 20 is driven by the telescopic mechanism 5 to extend out of the outer casing 1, the anti-collision rod 21 will first contact the extension slide rail 16, and then the anti-collision rod 21 will push the fan-shaped plate 14 to flip around the hinge seat 8. When the anti-collision rod 21 slides along the extension slide rail 16 and slides onto the guide plate 17, the fan-shaped plate 14 is almost fully opened, and the part where the telescopic mechanism 5 is slidably connected to the first slide rail 13 will contact the extension slide rail 16, thereby preventing the fan-shaped plate 14 from automatically closing when the observation instrument 20 is working, affecting the subsequent resetting of the observation instrument 20.

[0057] Through the above-mentioned scheme of the present invention, the outer casing 1 provided in the present invention can protect the observation instrument 20, and can prevent the observation instrument 20 from being in a naked state when not working. When it is necessary to observe the surface subsidence and rock movement, the outer casing 1 can be directly inserted into the surface gap or the pre-prepared hole, and the positioning mechanism 6 can be used to ensure the stability of the outer casing 1. At this time, the telescopic mechanism 5 can be used to pop the observation instrument 20 out of the outer casing 1 to achieve observation, and the fan-shaped plate 14 provided can be used synchronously with the anti-collision rod 21 and the telescopic mechanism 5, and can be automatically opened when the observation instrument 20 pops out of the outer casing 1, and automatically closed when the observation instrument 20 is reset.

The guide post 32 is slidably mounted on the adjusting plate 26, and an arc-shaped hole 40 is formed on the adjusting plate 26 so as to prevent the guide post 32 from sliding out of the adjusting plate 26. The adjusting shaft 24 drives the adjusting disk 26 to rotate, and the adjusting disk 26 can drive the guide column 32 to move through the arc hole 40. The movement of the guide column 32 can drive the slide bar 31 to slide in the slide groove 251, and finally realize the position adjustment of the support plate 35.

[0059] In order to enable the fixing plate 25 to be stably installed inside the outer casing 1, in this embodiment, a through hole 252 is opened in the center of the fixing plate 25, and the adjusting shaft 24 is arranged to pass through the through hole 252, and the adjusting shaft 24 is also rotatably installed in the through hole 252 through a connecting bearing (not shown in the figure), and a plug rod 29 is fixedly inserted on the outer wall of the fixing plate 25, and the end of the plug rod 29 away from the fixing plate 25 passes through the side wall of the outer casing 1, and the end of the plug rod 29 passing through the inner part of the outer casing 1 is also penetrated by a positioning member 30, and the positioning member 30 is fixedly installed on the outer wall of the outer casing 1, and a stopper 33 is fixedly installed on the end of the guide column 32 away from the sliding rod 31, and the two end ends of the support plate 35 arranged along the length direction thereof are hingedly connected with an extension plate 36, and a fixing block 37 is fixedly installed on the side of the arc plate 34 close to the sliding rod 31, and a tension spring 38 is installed between the fixing block 37 and the adjacent extension plate 36. When the outer casing 1 is inserted into the surface gap, the inner wall of the gap is an irregular shape, and the set extension plate 36 can be adaptively adjusted to a certain extent according to the shape of the inner wall of the gap through the tension spring 38, which can increase the overall fitting area between the support plate 35 and the extension plate 36 and the inner wall of the gap, thereby increasing the stability of the outer casing 1.

[0060] When the adjusting motor 22 drives the adjusting shaft 24 to rotate, the adjusting shaft 24 will synchronously drive the screw rod 28 to rotate, and the adjusting shaft 24 will adjust the sliding rod 31 through the adjusting disk 26 until the support plate 35 contacts the inner wall of the gap. In order to ensure that the telescopic mechanism 5 can continue to telescopically adjust when the support plate 35 contacts the inner wall of the gap, in this embodiment, a top groove 41 is provided on the inner side wall of the adjusting disk 26, and two adjacent top grooves 41 are connected by a connecting groove 42. A blind hole 43 is provided on the outer side wall of the mounting sleeve 39, and a top plate 44 is provided in the blind hole 43.

A tightening spring 46 is also provided in the blind hole 43, and the tightening spring 46 is arranged between the top plate 44 and the bottom wall of the blind hole 43. When the support plate 35 is not in contact with the side wall of the gap, the rotation of the adjusting shaft 24 will drive the assembly sleeve 23 to rotate synchronously. The support plate 35 is not in contact with the side wall of the gap. The tightening spring 46 can tighten the top plate 44 through the bottom wall of the blind hole 43, and then make the top ball 45 at the end of the top plate 44 tightly against the top groove 41. At this time, the assembly sleeve 23 can use the interaction between the top ball 45 and the top groove 41 to drive the adjusting disk 26 to rotate synchronously, and the adjusting disk 26 can adjust the position of the slide rod 31 through the arc hole 40. When the side walls of the gap are in contact, the support plate 35 can be pressed against the side walls of the gap until the support plate 35 can no longer go deeper into the side walls of the gap, and the adjustment disk 26 can no longer be rotated and adjusted. If the telescopic mechanism 5 has not yet fully extended out of the outer casing 1, and the adjustment shaft 24 continues to rotate, the top groove 41 on the inner wall of the adjustment disk 26 will begin to exert a reverse force on the top ball 45 and squeeze the top spring 46 until the top ball 45 slides into the connecting groove 42. Therefore, the assembly sleeve 23 does not affect the continued telescopic movement of the telescopic mechanism 5. In order to enable the top ball 45 to be stably moved and adjusted along the length direction of the blind hole 43, a guide block 47 is integrally provided on the outer wall of the top plate 44, and a guide groove 48 is provided along the length direction of the blind hole 43 on the inner wall.

[0061] Through the above scheme of the present invention, the sliding rod 31 provided in the present invention can drive the support plate 35 to pass through the strip hole 9 opened on the side wall of the outer casing 1, and then can contact the inner wall of the surface gap or the pre-dug hole, so as to locate the position of the outer casing 1, and the two ends of the support plate 35 are also hingedly installed with extension plates 36, and the extension plates 36 can perform a certain adaptive angle adjustment when the inner wall of the gap is irregular, thereby increasing the contact area of ​​the support plate 35 and the extension plate 36 with the side wall of the gap, and improving the stability of the outer casing 1. At the same time, the adjustment disk 26 used to adjust the extension and retraction of the support plate 35 is installed on the adjustment shaft 24 through the assembly sleeve 23, and the assembly sleeve 23 and the adjustment disk 26 are connected by the tightening spring 46 and the top ball 45. Such a structural design can enable the telescopic mechanism 5 to continue to extend and adjust when the support plate 35 contacts the inner wall of the gap and the observation instrument 20 has not reached the deepest point, thereby improving the observation effect.

[0062] Example 3: Please refer to Figure 1-23 , for the first and second embodiments, in order to enable the adjusting motor 22 to adjust the telescopic state of the telescopic mechanism 5 while driving the adjusting disk 26 to rotate, in this embodiment, the telescopic mechanism 5 includes a first sleeve 49, a second sleeve 50 is coaxially arranged inside the first sleeve 49, a third sleeve 51 is coaxially arranged inside the second sleeve 50, and the mounting seat 18 is fixedly mounted on the bottom end of the third sleeve 51, and a cross plate 52 is arranged at one end of the first sleeve 49 close to the adjusting disk 26, and the outer wall of the cross plate 52 is connected to the top of the first sleeve 49 through a fixing frame 53, and a screw sleeve 54 is fixedly installed through the center of the cross plate 52, and the screw sleeve 54 is installed on the outside of the screw rod 28. When the adjusting shaft 24 drives the screw rod 28 to rotate through the coupling 27, the screw rod 28 can drive the cross plate 52 to move inside the outer casing 1 through the screw sleeve 54, and a first slide bar 55 arranged along its length direction is fixedly installed on the outer wall of the first sleeve 49. The first sleeve 49 is slidably connected to the first slide rail 13. First notch grooves 56 are also provided on the side walls at both ends of the first sleeve 49. A first pulley 57 is rotatably installed in the first notch grooves 56. The two first pulleys 57 arranged in a line along the length direction of the first sleeve 49 are connected by a first belt 58.

Therefore, the movement of the first sleeve 49 will cause the first belt 58 to drive the first pulley 57 to rotate, and the first belt 58 is located inside the first sleeve 49 and is also connected to the outer wall of the second sleeve 50 through the second connecting block 62. Therefore, when the first belt 58 moves outside the first pulley 57, it will drive the second sleeve 50 to extend out of the first sleeve 49 through the second connecting block 62.

[0064] In order to enable the third sleeve 51 to extend out of the second sleeve 50, in the present embodiment, second notched grooves 63 are provided on the side walls at both ends of the second sleeve 50, and second pulleys 64 are rotatably installed in the second notched grooves 63.

The fourth connecting block 69 is arranged away from the mounting seat 18, and an end of the fourth connecting block 69 away from the third sleeve 51 is fixedly connected to the second belt 65. Following the same principle, when the second sleeve 50 is extended and retracted in the first sleeve 49, the second sleeve 50 will drive the second belt 65 to move through the second pulley 64 and the third connecting block 66. The second belt 65 will then drive the third sleeve 51 inside the second sleeve 50 to extend out of the second sleeve 50 through the fourth connecting block 69, so that the observer 20 at the end of the third sleeve 51 can be processed deep inside the gap.

[0065] In order to ensure that the third sleeve 51 can stably extend and retract inside the second sleeve 50, in this embodiment, a third slide rail 67 arranged along its length direction is fixedly installed on the inner wall of the second sleeve 50, and a third slide bar 68 arranged along its length direction is fixedly installed on the outer wall of the third sleeve 51, and the third slide bar 68 is slidably connected to the third slide rail 67.

[0066] Through the above-mentioned scheme of the present invention, the first sleeve 49, the second sleeve 50 and the third sleeve 51 are arranged in the present invention so as to realize synchronous extension and retraction according to the rotation adjustment of the screw rod 28, and the observation instrument 20 installed at the end of the third sleeve 51 can probe into the interior of the outer casing 1 to observe the inside of the hole or the surface gap, and the extension and retraction of the three sleeves are synchronously driven by the adjustment motor 22 for adjusting the support plate 35. Therefore, in actual use, it is only necessary to start the adjustment motor 22 to realize automatic positioning of the outer casing 1 and adjustment of the extension of the observation instrument 20.
